I'm building a lighting feature for my dissertation, I've finished my code, below if your interested. I'm looking to turn the prototype into an actual light. Does anyone have any advice for turning the breadboard into an actual product?

I'm unsure of what wires I need to replace the jumper wires, as the distance between the arduino and the actual light could be quite a distance in a live situation..

Also, does anyone know how many LED's you could power off of an Arduino Uno? I'm hoping to use at least 15-20I'm currently using 3mm Blue Diffused LED 5k MCD, but I'm looking to change these to 1.8-2.4v Red LED's...

int Val = 0; // variable used to store the value coming from the sensorint ledState = LOW; // ledState used to set the LEDlong previousMillis = 0; // will store last time LED was updated

long randNumber;

void setup() {

pinMode(LED1, OUTPUT); // LED is an OUTPUT pinMode(LED2, OUTPUT); // LED is an OUTPUT pinMode(LED3, OUTPUT); // LED is an OUTPUT pinMode(LED4, OUTPUT); // LED is an OUTPUT randomSeed(analogRead(2 & 3)); // Analogue pins are autmatically set as inputs

}

void loop() {

// READ SENSOR INOUT if ((Val = analogRead(0)) < 200) // read the value from the sensor // HIGHER NUMBER = MORE SENSITIVE // LOWER NUMBER = LESS SENSITIVE { analogWrite(LED1, 255-Val); // turn LED on at brightness set by sensor value analogWrite(LED2, 255-Val); analogWrite(LED3, 255-Val); // turn LED on at brightness set by sensor value analogWrite(LED4, 255-Val); delay(10); // stop the program for some time }

Length of wires depends on data rate, for DC wouldn't be a problem 10-20 meters. Maximum current Atmega328p - 200 mA, it can supply 10 leds with 20 mA each or 20 leds with 10 mA ( that will bring brightness to lower level ).For board projects, there is a CAD Eagle, just google it.

You can also do expresspcb.com, much quicker to figure out than eagle for a 1-time thing.

Here are some LED boards I did in expresspcb.group of 20, group of 3, 1 single. arduino Promini controls the transistors.2 of the LED boards are mounted in a box 50 feet from a controller, serial/ground and 12V power/ground got thru 4 conductor cable, arduino decodes message and turns LEDs on/off. 7805 provides 5V to arduino and the single LED, the 3 & 20 are powered from 12V.

You can get a length of 24/4 wire from home depot, they'll cut off what you need from a 500' roll.
